Din & Midi Wiring

This page gives information on wiring Din connectors for various purposes, including MIDI (Musical Instrument Digital Interface) connections.

Leads Direct sells and manufactures cables using a wide range of DIN standard connectors which you can view and purchase – the most common of these being MIDI and Keyboard and Mouse leads and cables.

DIN is short for Deutsches Insitut für Normung eV, the standards setting organization for Germany. A DIN connector is a connector that conforms to one of the many standards defined by DIN. DIN connectors are used widely in Hi-Fi, Audio Visual, Music and in Computers. For example, the keyboard connector for a PC is a DIN connector, as is the connector on a MIDI lead and an S-Video lead.

Whilst professionally made cables normally give better results than home-made equivalents, if you wish to make or repair your own cables the information below should help:

2-Pin DIN Speaker Connections

2 Pin DIN Plug and SocketThe 2-pin DIN is not a round connector like the more common 3 to 7-pin varieties.

Although the body is typically round, there is no shroud, and it simply has one wide spade-type of terminal and one round terminal.  The round pin is wired to the positive side of the amplifier output; the spade terminal to the negative:

Pin -> + (Positive)
Spade -> – (Negative)

Leads Direct can supply both 2 pin DIN speaker leads, and if required, the connectors to make your own.

If you prefer, we can make Custom Leads to your specific requirements, so that you get exactly what you need.

5-Pin DIN Audio Connections

There is no ‘standard’ pinout for 5-pin DIN audio connections, but there is a common configuration.  Viewed from the solder side of the plug (or from the face of the socket on the amplifier):

5 pin DIN Audio Connection

Pin 1  -> Left in
Pin 2  -> Signal ground
Pin 3  -> Left out
Pin 4  -> Right in
Pin 5  -> Right out

Vintage manufacturers that commonly used this audio configuration include Amstrad, Bang & Olufsen, Classic, Marantz, Naim, Quad, Sanyo, and many others.

DIN connections are no longer used for audio connections – all modern Hi-Fi equipment having moved to the RCA Phono pair as the connecting lead.  However, Leads Direct can supply a wide range of Custom Leads to suit your audio connection requirements.  Our friendly team will help you to determine your needs as required.

5-Pin DIN Midi Leads

Midi cables use a 180º 5-pin DIN connector with a single locating lug in the body, but only uses three of the pins. The cable should be screened with an overall Lap Screen. Pin 2 is connected to the Shield (also known as Screen or Earth), and the other pins are connected straight through:


  1.  -> Not Connected
  2.  -> 2 (Shield / Screen / Earth)
  3.  -> Not Connected
  4.  -> 4
  5.  -> 5

Our Standard and Oxygen Free Midi leads and cables are manufactured using this pin layout. Note that a few Midi products use one or two additional pins for their own purposes: in which case you should use a Standard 5-pin DIN pin out instead. There is no problem with having the extra connections if they are unused.


  1.  -> 1
  2.  -> 2 (Shield / Screen / Earth)
  3.  -> 3
  4.  -> 4
  5.  -> 5

Our Moulded Midi leads and cables use this layout with all pins connected, so they can also be used for audio and musical applications.

DIN 41612 Connectors

DIN 41612 standard describes multi-pin connectors that are often used as ‘backplane’ connectors, providing data transport between network equipment such as routers and switches.

The connectors may have up to three rows of contacts, each with 16 or 32 columns, allowing for 16, 32, 48, 64 or 96 contacts on a 0.1 inch (2.54 mm) grid pitch. The female connectors have IDC contacts rather than solder contacts, which helps to prevent heat damage to backplane equipment during installation.

A combination version of the connector (known as Type M) allows for a range of additional connections, including RF, signal and power connections to be included in the same connector.
